Alstroemeria named Stalis

ABSTRACT

A new Alstroemeria cultivar characterized in particular by its profuse year around production of very large flowers, the lower petals of which are distinguished by a combination of Spinel Red body portions with the outer petal portions being of a lighter Neyron Rose color which contrasts with the smaller upper petals, the larger of which are generally of a Rhodonite Red coloration with the central body portion of a bright Naples Yellow color, the upper petals being strongly marked by short, Brown pencil stripes which extend lengthwise of the petals from near the base to the petal tips, the smaller one of the upper petals has no Yellow and has only a few Brown pencil stripes mainly at the outer end of the petal; this plant is also distinguished by its medium height and its strong, upright and vigorous growth habit with abundant foliage.

BACKGROUND OF THE NEW PLANT

This new Alstroemeria plant originated as a seedling resulting from my crossing of selected plants which are individually identified members of my breeding stock maintained at Aalsmeer, The Netherlands, for developmental purposes. This particular seedling was selected by me for propagation because of the very large size of its blooms, the delicate Red and Pink coloration of its large lower petals, and the contrasting Yellow and darker Red coloration of the upper petals. Asexual reproduction of this seedling was done by me and under my direction at Aalsmeer, The Netherlands, by root division through several generations, which demonstrated conclusively that the distinctive characteristics of the parent seedling would hold true from generation to generation and appeared to be firmly fixed. Propagation of this new Alstroemeria variety is now being carried on at Aalsmeer, The Netherlands, by dividing root stock.

DESCRIPTION OF THE DRAWING

This new variety of Alstroemeria plant is illustrated by the accompanying photograhic drawing which, in full color, shows a blooming umbel of the plant with buds in the process of opening and with fully opened flowers, the color rendition being as nearly true to the specific colors as is possible to obtain by conventional photographic procedures.
